The Giant Robots Smashing into Other Giant Robots podcast is a weekly technical podcast discussing development, design, and the business of great products. Hosted by Ben Orenstein, who is joined each week by developers and designers from thoughtbot and beyond.

Ben Orenstein is joined by Josh Clayton, the maintainer of FactoryGirl, and a developer at thoughtbot. Ben and Josh discuss FactoryGirl: using it, its development progress, and features. What it's like to run an open source project, and how to contribute to open source effectively. Looking at your old code and being a better developer. Approaches to testing. And answer your questions about: FactoryGirl, How to write effective tests suites and whether integration tests are a scam, our process for upgrading between Rails versions, testing complex UI logic, and leaving code untested.
